What this page is

This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

Methodology

Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

Content

A boundary description is evolvable iff its claims are separated across the signature stack and each statement is routed by the boundary discipline matrix to its proper layer (Laws, Admissibility, Deontics/Commitments, Effects/Evidence), while preserving EntityOfConcern and Description-episteme / publication-carrier separation.
